Title: Semiconductor device
Inventor: WAKI YUTAKA
IPC: H01L21/60
Filed: 1984-08-10
Abstract: PURPOSE:To eliminate the need for wire bonding and enable a reduction in the size of a semiconductor integrated circuit, by forming an electrode lead portion on a semiconductor substrate so as to have a structure in which silver protuberant electodes are provided, and bonding leads for extenal connection and the silver protuberant electrodes by means of an electrically conductive paste. CONSTITUTION:An insulator layer 2 is formed on a semiconductor substrate 1, and electrodes 3 are formed on the layer 2. For example, silver of 2,000-5,000Angstrom  is deposited on the electrodes 3 to form a plating ground, and silver protuberant electrodes 4 are formed by jet plating in such a manner that the substrate 1 is connected to a negative electrode, while a silver plating solution is connected to a positive electrode, and the solution is sprayed on the electrodes 3. After the bonding surface of each lead 6 for external connection has been stamp-coated with an electrically conductive paste 7, the semiconductor integrated circuit chip os turned upside down, and the paste 7 on the lead 6 and the corresponding lead 4 are brought into close contact with each other. Under this state, the paste 7 is dried at high temperature, thereby bonding together the electrode 4 and the lead 6. Thus, the chip and the leads 6 are connected together in one unit, and in this state, sealing is effected by means of a resin 8.

Patent JP-H0218017-A (JP)
Title: Molding equipment of plastic material
Inventor: WADA MASAYOSHI
IPC: B29C31/04
Filed: 1988-07-07
Abstract: PURPOSE:To prevent the breakage of a material holding mechanism and the like from occurring and further deliver the exact amount of material by a method wherein the speed of the driving motor of a material fluidizing mechanism is decreased in response to the pressure at the material inlet of a cylinder. CONSTITUTION:After a piston 10 compresses a compression spring, the spring pressure increases as the compression spring 17 is compressed, resulting in increasing the pressure at the material inlet of a cylinder 8. Thus, the speed of a driving motor 3 lowers in response to the pressure at the material inlet of the cylinder 8, resulting in stopping the driving motor 3 at a pressure just before the maximum compression of the compression spring 17. Further, the fluidizing mechanism 2 is controlled by both a servo motor and a digital switch. Furthermore, a relief valve 27 is provided at the delivery port 25 of a delivery mechanism 4. The relief pressure of the valve 27 is set higher than the vapor pressure of the material at the delivery port at its melting temperature so as to make the delivery pressure of the material higher than its vapor pressure, resulting in eliminating bubbles developing through vaporization in the material and consequently delivering the exact amount of the material.

IPC: G01B7/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a touch probe of three-dimensional measuring system which senses the contact of a stylus with an object to be inspected from electrical continuity between the two members upon impression of a voltage between them, wherein the contacting part is prevented from oxidative corrosion.

Patent JP-H0332246-A (JP)
Title: Traffic control system
Inventor: HYODO MUTSUO
IPC: H04L12/42
Filed: 1989-06-29
Abstract: PURPOSE:To efficiently use transmission lines by setting a counter field to a token, using the counter field of the token, measuring the traffic, and using the measured traffic to control the frame transmission. CONSTITUTION:When a frame transmission request exists in its own node, after a 1st token control section 100 detects and acquires a token, a frame transmission control section 400 sends a frame. After the end of frame transmission, the frame transmission control section 400 commands the release of the token to a 2nd token control section 500. The 2nd token control section 500 stores the value of the counter field when the token is acquired from a loop 600 and increments the counter field when the token is returned to the loop 600. On the other hand, a traffic measuring section 200 samples the counter field of the token passing through its own node for a prescribed period to recognize the traffic on the loop 600. Thus, the efficient use of the transmission line is attained.

Title: Discriminating device for long object
Inventor: ENDO MASAHIRO
IPC: B07C5/10
Filed: 1989-06-30
Abstract: PURPOSE:To automatically and continuously decide the length and the bending of a long object by keeping a still picture within a prescribed range set on the basis of the root of the long object and deciding the length of the long object based on the presence or absence of the shadow of the long object formed on a length deciding reference line. CONSTITUTION:When a long onion 2 reaches an appropriate position before a flash light 5 on a conveyor 1, the flash light 5 emits the light after detecting the onion 2 via a sensor. The light of the flash light 5 transmits through a light diffusing plate 6 and irradiates evenly the surface of the onion 2 opposite to the plate 6. Then the light reaches a camera 7 set opposite to the flash light 5 and a shadow formed when the light is cut by the onion 2 is detected as a still picture. The shadow of the onion which is detected and recognized is outputted through a CCD as the electric signals. Receiving these electric signals, a picture processing/deciding device 8 decides the length, the thickness, the bending degree, etc., of the onion 2. Thus it is possible to perform the automatic and continuous discrimination, allocation and store of the onions 2.

Abstract: PROBLEM TO BE SOLVED: To automatically obtain index pictures of photographed and recorded pictures by a camcorder as still pictures summarizing a plurality of reduced pictures that result from dividing the photographed and recorded pictures at a prescribed interval independently of the length of each scene. SOLUTION: When starting photographing, a moving picture from a camera is recorded on a tape 105. A memory control circuit 102 captures an image signal from a camera signal processing circuit 103 every second and stores the image signal to memories 101-0 to 101-8 as still pictures sequentially one image pattern each. When the photographing time exceeds 8 seconds, the captured interval is doubled and the picture is captured and overwritten on the memories having stored preceding pictures every 2-second. Furthermore, when the photographing time exceeds 16 seconds, the captured interval is further doubled every 4-second similarly to above.  After the end of photographing, the captured pictures are respectively reduced and rearranged and appended on the tape 105 as index still pictures realizing multi-image pattern consisting of three reduced pictures longitudinally and laterally on one screen.

Filed: 1990-06-27
Abstract: PURPOSE:To perform tests of electric characteristics and sensing of dispersion in the leads by supporting each electrode with a spring, and using elongation and contraction of the spring to cause the electrode to touch a sensor. CONSTITUTION:An arrangement according to the present invention comprises a socket outer wall 6 which accommodates a semiconductor package 1 having leads 2a, 2b, electrodes 3a, 3b which are set on this outer wall 6 through a support spring 4 at the same level as all pins, and a sensor 5 mounted on the outer wall 1 to send a signal when these electrodes 3a, 3b come in contact.
